1.1.1.105 | evolution | RDHs that catalyze the interconversion of retinal and retinol involved in rhodopsin turnover are members of the family of short chain dehydrogenase/reductases | Mus musculus |
1.1.1.105 | malfunction | outer segments of rods deficient in Rdh8 fail to reduce all-trans-retinal. Following exposure to light, a leak of retinoids from outer to inner segments is detected in rods from both wild-type and knock-out mice. In cells lacking Rdh8 or Rdh12, EC 1.1.1.300, this leak is mainly all-trans-retinal, overview. Retinal reductase activity is lost in RDH12-deficient mutants | Mus musculus |
1.1.1.105 | physiological function | in vertebrate rod cells, retinoid dehydrogenases/reductases are critical for reducing the reactive aldehyde all-trans-retinal that is released by photoactivated rhodopsin, to all-trans-retinol. Reduction of all-trans-retinal in vertebrate rod photoreceptors requires the combined action of RDH8 and RDH12. RDH8 in the outer segment provides most of the activity needed to reduce all-trans-retinal generated by the light response, overview | Mus musculus |
1.1.1.300 | evolution | RDHs that catalyze the interconversion of retinal and retinol involved in rhodopsin turnover are members of the family of short chain dehydrogenase/reductases | Mus musculus |
1.1.1.300 | malfunction | loss-of-function mutations of RDH12 cause retinal degeneration in some forms of Leber congenital amaurosis. Outer segments of rods deficient in Rdh12 show no altered phenotype. Following exposure to light, a leak of retinoids from outer to inner segments is detected in rods from both wild-type and knock-out mice. In cells lacking Rdh8, EC 1.1.1.105, or Rdh12, this leak is mainly all-trans-retinal, overview. Retinal reductase activity is lost in RDH8-deficient mutants | Mus musculus |
1.1.1.300 | physiological function | RDH12 activity in the photoreceptor inner segments is also key enzyme function. RDH12 in inner segments can protect vital cell organelles against aldehyde toxicity caused by an intracellular leak of all-trans-retinal, as well as other aldehydes originating both inside and outside the cell | Mus musculus |
